Definitions
- the invention relates to a method for determining an operating stress of a component during operation of the component and a rail vehicle for carrying out the method.
- the detection of the operating stress of brake disks and brake pads or linings of a rail vehicle during maintenance work takes place in a prescribed, regular maintenance interval. Further observations may be made after a particular event, such as emergency braking, from a high speed, as visual inspection to check cracks or deformations of the brake may have become necessary. On the other hand, could be dispensed with a little-claimed brake on a regular inspection of the brake or the maintenance interval can be adjusted accordingly.
- pamphlet US 2003/0056995 A1 discloses a method for determining an operational stress of a component during operation of the component according to the preamble of independent claim 1.
- the invention has for its object to propose a method to detect operating stresses of a component during operation of the component.
- Method step a is carried out in particular during an adjustment phase, whereas the calculation rule according to method step e is provided for determining the operating load of the component during operation of the component during an operating phase.
- the measured values for the predetermined measured variables are recorded during the operation of the component during an adjustment phase for the at least n different operating modes.
- the calculation rule is provided to occur during a subsequent operating phase to determine the operating stress, without directly and directly, in particular by measuring to capture.
- the component is in particular a component of a vehicle, in particular a rail vehicle.
- Vehicles are used to transport people and / or goods.
- land vehicles are also watercraft, aircraft and spacecraft, as well as their mixed forms includes.
- the operating stress of the component includes wear of the component. If wear is determined as operating stress, the component could also be referred to as wear part. Wear is a progressive loss of mass of a body, especially on its surface, called, which is usually caused by mechanical causes. Wear is sometimes called wear. Wear is one of the main causes of component damage and the associated failure of machinery and equipment. Wear parts are replaceable components that are subject to wear under normal conditions of use.
- the operating stress of a component is basically measurable. Often, however, not during operation of the component. Therefore, the operating load is to be indicated by a measurand.
- measured values of measured variables are recorded which have a direct or indirect influence on the operating stresses.
- the measured variables are used to map influencing factors or wear factors. These influencing factors influence the operating load directly or indirectly, but are not equal to the operating load.
- the operating stress by means of the measured values for the influencing variables, which are indicated by the measured variables.
- various mathematical operations may be necessary.
- effect operands are specified for the characterization of the operating stress. Effect operands do not have to be directly the subject of a measurement - they are not necessarily measured variables. They can also be determined by physically known or fixed mathematical relationships from measured quantities to which immediate measurements apply. An effect operand is determined according to a predetermined calculation rule from at least one influencing factor. The effect operands are thus dependent on the mentioned measured values and are determined by a predetermined calculation rule or mathematical formula.
- the operation operands are thus determined by means of predetermined functions and according to a development of the invention by means of predetermined mathematical operations, the operands of the mathematical operations used being the measured values recorded in method step a for the predetermined measured variables.
- Other operands may optionally assume constant values, which are specified, in particular depending on the corresponding operating mode. Further developed, only constants and the measured values acquired in method step a serve as operands for determining the effect operands.
- the component is, for example, a brake disk, a brake pad or a brake lining of a brake, in particular a hydraulic or compressed air-operated brake, of a rail vehicle, for example the braking time and / or the braking distance and / or the brake pressure in a brake cylinder Brake of the rail vehicle and / or the instantaneous speed of the rail vehicle continuously or discreetly measured with a predetermined measurement frequency and thus recorded measured values for these measurements using appropriately suitable sensors.
- a firstidesoperand can then, for example be determined that an integral over the braking distance of the square of the measured values of the brake pressure is formed.
- a product of the brake pressure and the instantaneous speed of the rail vehicle can be integrated via the braking distance.
- a third mode of operation could result from the integration of brake pressure across the braking distance.
- m 3 effect operands
- a first mode of operation then includes, for example, normal braking from predetermined speeds when approaching a stop.
- a second mode of operation may include emergency or rapid high speed braking.
- a third mode of operation then includes, for example, emergency or rapid low speed brakes, such as may occur when people get on the tracks at stops just before the rail vehicle stops.
- Operating modes can differ only marginally.
- measured values of a first operating mode over a predetermined period or a predetermined distance could be determined, for example, from one location B to another C, in normal operation of the component with several moderate deceleration and a few quick brakes.
- the reverse path from location C to location B during normal operation of the component could serve as a second mode of operation, even under very similar operating conditions. It is important that the component is operated in separate and different operating modes and that the measured values are recorded and subsequently evaluated.
- the operating modes can also differ from each other only by different environmental conditions, as long as the environmental conditions are also recorded in measured values and used to determine the effect operands. For example, the influence of climatic conditions could be taken into account.
- the measured values are eg temperature or humidity detected.
- the determination of the effect operands is carried out as above in a predetermined, in particular fixed, dependence on the measured values acquired over the predetermined time, for example over the elapsed time of the intended operation of the component in the corresponding operating mode.
- the determination of the effect operands takes place exclusively by means of the acquired measured values and constants and mathematical operations.
- the effect operands are then weighted with weighting factors, wherein each effect operand is multiplied by a weighting factor.
- the number of weighting factors is equal to the number of effective operands. This happens separately for each operating mode.
- the sum of the weighted effect operands is then equated, for each operating mode, with the operating load measured for the corresponding operating mode. In n operating modes, such equations are obtained.
- the system of equations is solved and the values for the weighting factors a 1 to a m are obtained.
- a weighting factor becomes zero.
- the weighting factors a 1 to a m take values from the set of real numbers, such as the positive rational numbers.
- Both the calculation instruction for determining the operating stress and the calculation rule for the effect operands as well as the determined values for the weighting factors are stored in a memory in order to provide them for a later evaluation during the operating phase.
- the method step f is carried out during the operating phase, which follows the adjustment phase.
- the predetermined measured variables from method steps a and f are identical.
- the adjustment phase can be carried out with one or more identical components, while in the operating phase further components identical to the components of the adjustment phase are used.
- the calculated calculation rule including the weighting factors therefore does not only apply to an individual component, but also to all components of a group of identical components.
- the component can be exchanged with a component from a common group of identical components.
- the process steps are in the Justierphase a to e, for example, performed with a first brake pad. Subsequently, the first brake pad is replaced by a different from the first brake pad, but taken from a common group identically formed brake pads, second brake pad, with which the method steps f to h are performed.
- the operating stress of the component determined in method step h during operation of the component can be output. For example, it can be displayed to a driver or it is transmitted to a central control center and displayed there for further processing and evaluation.
- the output of the determined operating stress can also be carried out as a function of the determined operating stress. If it exceeds a predetermined threshold value, it is displayed and / or, if appropriate, an alarm signal is output. Below the threshold value, no output of the determined operating load and / or possibly an alarm signal occurs.
- the operating stress can be determined discretely during operation of the component during the operating phase or at predetermined time intervals. A determination can also be made as a function of predetermined events, for example, emergency braking from high speeds.
- a measured values of k predetermined measured variables can be detected during operation of the component, where k is a natural number greater than or equal to m and thus k ⁇ m.
- k is a natural number greater than or equal to m and thus k ⁇ m.
- a larger number of effect operands could be formed from a small number of measured variables. Then k ⁇ m would hold.
- An inventive rail vehicle for carrying out the method according to the invention comprises at least one sensor for detecting the measured values relative to the predetermined measured variables, at least one memory for receiving and outputting the weighting factors and at least one evaluation unit, in particular a microcontroller, for determining the operating stress of the component during operation of the component by means of the provided calculation rule.
- the at least one sensor is suitable for acquiring measured values for the predetermined measured variables and designed accordingly.
- the invention provides a computer program product for carrying out the method according to the invention.
- the computer program product comprises a software code which is suitably designed to carry out the method according to the invention if it is carried out on a suitable data processing system, which is in particular comprised by the rail vehicle according to the invention.
- the object underlying the invention is achieved by a computer-readable data carrier on which the computer program product according to the invention is deposited.
- the computer-readable data carrier can likewise be encompassed by the rail vehicle, in particular it is encompassed by the memory for receiving and outputting the weighting factors of the vehicle.
- a manufacturer of rail vehicles manufactures a first of identical rolling stock of a fleet. It includes a compressed air operated brake system. After its completion, it is subjected to various test drives on a test track.
- measured values for predetermined measurement variables are first detected for each operating mode.
- the measured variables are not equal to the operating stress of the brake lining to be determined.
- As operating stress of the brake lining here is the decrease in the thickness of the brake pad after each Operating the rail vehicle detected in the predetermined operating modes.
- Further examples of operating stresses may be: the wear or the groove depth of a brake disk, but also the current operating temperature of the brake disk.
- As measured variables during operation however, for example, the instantaneous vehicle speed, the braking distance or the time and the current pressure in a brake cylinder are specified.
- the vehicle is thus operated in a predetermined first operating mode during the adjustment phase, during operation the measured values are recorded for the predetermined influencing factors and the operating load is measured after operation. Subsequently, during the adjustment phase, the vehicle is operated in a further, second operating mode different from the first operating mode, the measured values for the predetermined influencing factors are recorded during operation and the operating load is measured after operation.
- an equation for calculating the operating stress for each operating mode can be set up.
- the respective effect operands W 1 to W 3 are weighted with weighting factors a 1 to a 3 for each of the three operating modes such that the decrease of the thickness of the brake pad directly detected for each operating mode is equal to a sum of the weighted effect operands.
- the decrease in the thickness of the brake pad is referred to below as z.
- z a 1 * W 1 + a 2 * W 2 + a 2 * W 2 ,
- z 1 a 1 ⁇ ⁇ 0 s 1 p 1 2 d s 1 + a 2 ⁇ ⁇ 0 s 1 v 1 ⁇ p 1 d s 1 + a 3 ⁇ ⁇ 0 s 1 p 1 d s 1
- z 2 a 1 ⁇ ⁇ 0 s 2 p 2 2 d s 2 + a 2 ⁇ ⁇ 0 s 2 v 2 ⁇ p 2 d s 2 + a 3 ⁇ ⁇ 0 s 2 p 2 d s 2
- z 3 a 1 ⁇ ⁇ 0 s 3 p 3 2 d s 3 + a 2 ⁇ ⁇ 0 s 3 v 3 ⁇ p 3 d s 3 + a 3 ⁇ ⁇ 0 s 3 ds ,
- the indices also took account of the three different operating modes.
- the first operating mode provided here a braking with a predetermined small jerk and a predetermined average braking acceleration from a mean predetermined speed to a stop.
- the braking required the braking distance s 1 . It led to a decrease in the thickness of the brake disc of z 1 .
- the second operating mode provided here a braking with a predetermined large jerk and a predetermined large deceleration from a high predetermined speed to a stop.
- the braking needed the braking distance s 2 and led to a Decrease in the thickness of the brake disc of z 2 .
- the third mode of operation provided braking with a predetermined large jerk and a predetermined large deceleration from a low preset speed to a stop, which required a braking distance s 3 and led to a decrease in the thickness of the brake disk of z 3 .
- the instantaneous rate of braking of the first mode of operation has been designated v 1 .
- the instantaneous pressure in the brake cylinder was designated p 1 during the braking of the first operating mode.
- the instantaneous speeds and the instantaneous brake pressures in the second and third mode braking are designated v 2 and v 3 and p 2 and p 3 , respectively.
- one mode of operation may also include multiple identical stunts.
- the vehicle is then accelerated several times to the predetermined speed and braked in a predetermined manner. Only then is the operating load, in this case the decrease in the thickness of the brake pad, measured. Advantage is a higher informative value.
- the values for the weighting factors and the aforementioned calculation rules are stored in a computer-readable data carrier of each rail vehicle of the fleet of identical rail vehicles of the manufacturer. After delivery of the rail vehicles to the customer they are put into operation.
- the operating phase of a Rail vehicle includes the subsequent trips in normal operation of the customer including the intended operation of the brakes.
- the rail vehicles are each equipped with mutually different, but identical brakes. Nevertheless, with the stored data and with the measured values acquired during operation in the operating phase, the operating load can be determined for the given measured variables. An exchange of brake pads with identical brake pads is irrelevant.
- measured values for the predetermined measured variables during operation of the component which measured variables are not equal to the operating load of the component to be determined, are first recorded. Subsequently, the effect operands W 1 to W m in a predetermined dependence on the measured values and the operating stress of the component during operation of the component are determined by means of the provided calculation rule with the obtained weighting factors.
- the calculation rules and the weighting factors are read from the memory or the computer-readable data carrier for further processing and processed in the evaluation unit.
- the operating stress of the component during operation of the component in an operating phase can be indirectly estimated by the inventive method, without directly detect them, even if a measurement of operating stress during operation is not possible, so the operating load not is directly detectable. Measurements of the wear factors or influencing factors as predetermined measured variables during the operation of the component are sufficient. A model of the operating load is based on this. During operation of the component in the operating phase, the method according to the invention is thus free from an immediate detection of the operating stress. The model depicts the influence of single effect operands on the operating load in different operating modes.
- a signal such as an alarm, may be issued when a predetermined operating load limit is exceeded, thereby warning the driver in good time of any failure of the component.
- the determined operating stress can also be further processed, for example for planning inspections or even for adapting the inspection intervals.
- an estimation of the expected life of the component is possible and a quasi-continuous load control at runtime of the component.
- the influence of environmental conditions for example climate
- the influence of environmental conditions can also be taken into account. Since the component can be operated as intended under different environmental conditions, it is also possible to measure external conditions, e.g. to the air temperature or humidity of the environment of the component, and the effect operands can be determined accordingly as a function of the measured values for the environmental conditions.
- the determined calculation rule is valid for components from a group of identical components in identical vehicles and can be extended to generic vehicles. Thus, only one adjustment phase is necessary. This is especially advantageous for operating stresses that are very expensive to capture. Also, the operation of the component in different operating modes during the Justierphase itself need not be performed with the same component, but only with a component from a group of identical components, from which then the component comes from the operating phase.
- the method according to the invention can also be used to determine optimum operating modes for the component.
- the method comprises a corresponding method step following the method step e.
